“…To effectively protect urban areas from acoustic pollution, acoustic screens are used that are installed in the path of sound wave propagation. Most often they are a structure containing a foundation base, a basement, a bearing base, transverse struts, longitudinal profiles and sound-reflecting or sound-absorbing panels, in some cases it is proposed to use both types of panels [13][14][15][16]. As a result of the interaction of "И-II" and the acoustic field "A-II.1", two sound fields are formed:…”

The article is devoted to the study of the air acoustic pollution reduction process for brick manufacturing enterprises based on the physical and energy approach based on the theory of dispersed systems. The authors performed physical modeling of the process taking into account the properties of all the objects taking part in it at each stage and the features of the space in which it is implemented. Based on the constructed model, a mathematical description of the probability of the process and its effectiveness is obtained.

“…With the rapid development of modern industry, transportation and urban construction, noise pollution has become critical issues in modern society [ 1 ]. Noise and vibration will not only reduce industrial production efficiencies, but also be harmful to workers in industrial and noisy environments [ 2 ]. Therefore, reducing the harm caused by noise and vibration has drawn increasing attention in the fields of scientific research, industrial and so on [ 3 , 4 , 5 ].…”

Improved Mechanical and Sound Absorption Properties of Open Cell Silicone Rubber Foam with NaCl as the Pore-Forming Agent

Porous materials hold great potential in the field of sound absorption, but the most abundantly used materials, such as Polyurethane (PU) foam and polyvinyl chloride (PVC) foam, would inevitably bring environmental harms during fabrication. In this study, the nontoxic addition-molded room temperature vulcanized silicone rubber is chosen as the matrix, and NaCl particles are chosen as the pore forming agent to prepare open cell foams via the dissolve-separating foaming method. The effect of different amounts of NaCl (0–100 phr) on the cell structure, mechanical and sound absorption properties is investigated and analyzed. The results indicate that the cell structure could be tailored via changing the addition amount of NaCl, and open cell silicon rubber foams could be achieved with more than 20 phr NaCl addition. Open cell silicon foams show the most effective sound absorption for sound waves in middle frequency (1000–2000 Hz), which should be attributed to the improved impedance matching caused by the open cell structures. Additionally, the mechanical properties, including hardness, tensile strength and corresponding elastic properties, gradually decay to a steady value with the increasing addition amount of NaCl. Therefore, open cell silicone rubber foams are capable of sound absorption in middle frequency.

“…Mathematical multi-criteria optimization methods are usually used to plan the reduction of the impact of noise coming from various sources such as road and rail transport, construction and operations, or resulting from human life. In addition, they are based on many purposes [40][41][42][43]. In this way, an attempt is made to reduce the impact of noise along with optimizing the costs of decisions and possible implementation.…”

This paper addresses the problem of noise in spa protection areas. Its aim is to determine the delimitation of the areas that exceed a permissible noise level around the sanatorium on the example of a health resort in Inowrocław. The determination of the exceedance of permissible noise levels allows us to develop directly effective local policy tools to be included in planning documents. In order to reduce noise infiltration, it is important to define environmental priorities. Taking into account their impact on the health of users in the protection area, environmental priorities enable us to introduce additional elements to street architecture. In order to properly manage space, in accordance with the idea of sustainable development, zones of environmental sensitivity-and their socio-environmental vulnerability-have been designated for assessing damage (exceeding permissible noise in health facilities) and defining methods of building resilience (proper management). This has provided the basis for a natural balance optimized for the people living in these areas. To achieve the goal above, non-linear support vector machine (SVM) networks were used. This technique allows us to classify the linearly inseparable data and to determine the optimal separation margin. The boundaries of the areas which exceeded permissible noise levels (separation margin) were estimated on the basis of noise pollution maps, created by means of the SVM technique. Thus, the study results in establishing buffer zones where it is possible to use varied land utilization in terms of form and function, as described in the planning documents. Such an activity would limit the spread of noise.Sustainability 2019, 11, 4199 2 of 17 it is important to properly manage and recognize social, environmental and health vulnerabilities. "Noise sensitivity" is defined as an individual and increased probability of perceiving sounds as unpleasant [8][9][10][11]. Moreover, getting used to excessive noise levels causes indifference, which is caused by exposure to a hazardous situation [12][13][14][15][16].Noise can be characterized by its source (e.g., anthropogenic or natural causes) or by specific physical values, such as power, intensity, frequency or duration. It should be noted that its relevant parameters refer not only to strictly objective values considered to be unpleasant or harmful but also, to the same extent, to the places where common sounds will cause unwanted or disturbing effects [17][18][19]. Organized urban spaces are treated like resources directly used by local residents. The conditions of these spaces decide also on the possibilities for creating a proper base for planners who, to a greater or lesser degree, introduce quantitative and qualitative changes in the area [20,21].It is important then, to analyze the acoustic situation. The determination of physical parameters such as density, open spaces, their shape, the greenery and the location of the buildings has a significant effect on the noise spread in the environment [18,22]. Maps are a...
